[FFmpeg-user] A question on NVENC's A53CC support

[Dennis Mungai]

Hello there,

According to this commit
https://git.videolan.org/?p=ffmpeg.git;a=commit;h=5a88e8c36581fed09c7db6dc7229f1fd9ab5559d
, A53CC support was added to the NVENC encoder.

For lavc, its' also enabled by default:
https://ffmpeg.org/pipermail/ffmpeg-devel/2016-September/199200.html

Is it safe to assume that closed captioned support is enabled by default in
the encoder, or is it necessary to pass the -a53cc flag to explicitly
enable the feature?
